The document provides an overview of Microsoft Azure, including what it is, its service models, and how it can be used to deploy Microsoft Dynamics AX. Azure is Microsoft's cloud platform that offers integrated computing, storage, networking and application services. It has three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Dynamics AX 7 will deploy on Azure Infrastructure as a Service using SQL Azure and replace the Windows client with a new browser-based interface. Lifecycle Services on Azure can be used to automatically deploy Dynamics AX environments for development, testing and demonstrations.
